AI Technical Summary
Existing technologies fail to effectively consider the upper limit of manufacturing service capabilities and the differences in heterogeneous tasks in manufacturing service portfolios distributed across regions, resulting in shortcomings in time and cost control of service portfolio solutions. This is especially true for manufacturing enterprises with multiple tasks and multiple production bases, making it difficult to meet the production needs of various products.
A multi-objective optimization model for manufacturing service combinations under cross-regional collaboration is constructed and solved using the NSGA-II algorithm. Considering the characteristics of limited manufacturing service capabilities and heterogeneous tasks, the optimization objective is to minimize the maximum completion time and total cost. Combining vertical and horizontal priority relationships, a heuristic search mechanism is designed to improve the quality of the solution.
It improves the quality of manufacturing service portfolio solutions, enabling more effective fulfillment of the time and cost requirements of multi-task, multi-production-base manufacturing enterprises, and optimizes manufacturing service portfolios under cross-regional collaboration.
